Get ready for some confusion in the 205: a new area code is coming to Central Alabama. 

AT&T announced a new area code to overlay the current area served by the existing 205 area code. The new 659 area code will apply only to new customers within the area, so those with a 205 number will not see a change in their existing phone numbers. Local calls made to a 659 number will require the entire seven-digit phone number to complete the call, and calls made from a 659 number to a 205 number will also require all seven digits. As of October 12, 2019, all calls made without the correct procedure will not be completed.
